280 Reviews—Jack and Etheridge—Geology of Queensland. 
From the introductory chapter we learn that the Hastern portion 
of Queensland, comprising from one-third to nearly one-half its area, 
consists of the remnant of a lofty table-land which reaches an eleva- 
tion of over 5,000 feet, and from its Hastern edge has a short steep 
slope to the Pacific. This coast region consists of granites, syenites, 
basic igneous rocks, and of a series of stratified rocks, which in the 
lower portions are metamorphosed to a variable extent. The 
Western interior of the country presents a totally different aspect ; 
for the table-land slopes away gradually towards the Gulf of Carpen- 
taria and the south-west boundary of the colony, and the area 
consists of soft stratified Cretaceous rocks which form a good soil, 
though its fruitfulness is marred by a deficiency of rainfall. In 
some districts there are remnants of table-lands of the so-called 
Desert Sandstone, which apparently formerly extended over the 
Cretaceous clays, but fortunately has been largely denuded. 
The list of the Geological Formations recognised in Queensland is 
not nearly so long as that of most European countries, but the 
authors state that the order of succession bears a general and striking 
resemblance to that worked out in Hurope, though owing to the 
great distance separating these countries, they do not claim more 
than a homotaxial relationship for the Queensland formations which 
they have disposed under European names. Beginning at the top 
of the series, the post-Tertiary is represented by Bone-Drifts, Cave- 
Breccias, Sand-Dunes, etc.; in the Tertiary only the Pliocene and 
Miocene are doubtfully recognized; the former by the Upper, the 
latter by the Lower Voleanic and Drifts. In the Mesozoic Group, 
the Desert Sandstone, considered as Upper Cretaceous, rests uncon- 
formably on the Rolling Downs of Lower Cretaceous Age. Below 
these come the Ipswich rocks, forming the Upper Division of the 
Trias-Jura, whilst the Burrum series constitutes the Lower Division. 
Then comes in a strong unconformability, and below it the Bowen, 
Star, and Gympie divisions of the Permo-Carboniferous. Between 
these and the Burdekin group of Middle Devonian age there is 
another unconformity. The Burdekin is the lowest Formation con- 
taining determinable fossils, below it there are beds of stratified 
rocks succeeded by slates, schists, ete., of undetermined age. 
Successive chapters are devoted to the description of the characters, 
the economical features, the fossils, and other particulars relating to 
each of these groups, commencing with the Plutonic and Meta- 
morphic Rocks. 
Some of the granites and syenites are stated to be distinctly meta- 
morphic in character ; alternate layers of coarser and finer material 
betraying an originally sedimentary origin. Tin, Silver-lead, Bismuth 
and Gold mines are present in some of the granite areas. 
The metamorphic rocks are considered to have been originally 
limestones, conglomerates, siliceous and felspathic sandstones, clay- 
shales and mudstones, which are now generally thrown into sharp 
folds and locally metamorphosed into marbles, quartzites, grey- 
wackes, mica- and tale-schists, lydian stone or even into serpentines, 
diorites, hornblende and tourmaline gneisses. By Daintree and
